Exercise 10.2

Refer to pages 6-7 for exercise 10.2 in the PDF 

1. Construct $\vartriangle XYZ$ in which $XY = 4.5$cm, $YZ = 5$cm and $ZX = 6$cm.

Ans: To construct: $\vartriangle XYZ$, where $XY = 4.5$cm, $YZ = 5$cm and $ZX = 6$cm.

Steps of construction:

(a) Draw a line segment $YZ = 5$cm.

(b) Take $Z$ as centre and radius as $6$cm, draw an arc.

(c) Similarly, taking $Y$ as centre and radius $4.5$cm, mark another arc that intersects the first arc at point $X$.

(d) Join $XY$ and $XZ$.

Triangle XYZ


This is the required $\vartriangle XYZ$.

2. Construct an equilateral triangle of 5.5 cm.

Ans: To construct: A $\vartriangle ABC$ where $AB = BC = CA = 5.5$cm.

Steps of construction:

(a) Draw a line segment $BC = 5.5$cm.

(b) Taking points $B$ and $C$ as centres and radius $5.5$cm, draw arcs which intersect at point $A$.

(c) Join $AB$ and $AC$.

Triangle ABC

This is the required $\vartriangle ABC$.


3. Draw $\vartriangle PQR$ with $PQ = 4$cm, $QR = 3.5$cm and $PR = 4$cm. What type of triangle is this?

Ans: To construction: $\vartriangle PQR$, in which $PQ = 4$cm, $QR = 3.5$cm and $PR = 4$cm.

Steps of construction:

(a) Draw a line segment $QR = 3.5$cm.

(b) Take $Q$ as centre and radius as $4$cm and draw an arc.

(c) Similarly, take $R$ as centre and radius as $4$cm and draw another arc which intersects the first arc at $P$.

(d) Join $PQ$ and $PR$.

Triangle PQR

The triangle obtained is the isosceles $\vartriangle PQR$.


4. Construct $\vartriangle ABC$ such that $AB = 2.5$cm, $BC = 6$cm and $AC = 6.5$cm. Measure $\angle B$.

Ans: To construct: $\vartriangle ABC$ in which $AB = 2.5$cm, $BC = 6$cm and $AC = 6.5$cm.

Steps of construction:

(a) Draw a line segment $BC = 6$cm.

(b) Taking $B$ as centre and radius $2.5$cm, draw an arc.

(c) Similarly, take $C$ as centre and radius $6.5$cm then draw another arc which intersects the first arc at $A$.

(d) Join $AB$ and $AC$.

(e) Now measure angle $B$ with the help of a protractor.

Triangle ABC right-angled at B

It is the required $\vartriangle ABC$ where $\angle B = {90^ \circ }$.
